Perturbative instability of cosmology from quantum potential
Apart from its debatable correctness, we examine the perturbative stability of the recently proposed cosmology from quantum potential. We find that the proposed quantum corrections invoke additional…

The general dynamic equations of quantum corrected thin shell wormholes by applying Darmois–Israel formalism are derived. The stability analyses of wormhole with a generalized cosmic Chaplygin gas, a…
Quantum corrected Schwarzschild thin-shell wormhole
Recently, Ali and Khalil (Nucl Phys B, 909, 173–185, 2016), based on Bohmian quantum mechanics, derived a quantum corrected version of the Schwarzschild metric. In this paper, we construct a quantum…

On the correctness of cosmology from quantum potential
We examine in detail the cosmology based on quantal (Bohmian) trajectories as suggested in a recent study arXiv:1404.3093[gr-qc]. We disagree with the conclusions regarding predicting the value of…
Quantum Hǒrava-Lifshitz cosmology in the de Broglie–Bohm interpretation
Classical and quantum Friedmann–Lemâıtre–Robertson–Walker universes filled with noninteracting radiation and dust fluids are considered in the framework of Hořava–Lifshitz gravity theory. The…

Massive Gravitons on Bohmian Congruences
Taking a quantum corrected form of Raychaudhuri equation in a geometric background described by a Lorentz-violating massive theory of gravity, we go through investigating a time-like congruence of…
Quantum cosmology of a Hořava–Lifshitz model coupled to radiation
In the present paper, we canonically quantize a homogeneous and isotropic Hořava–Lifshitz cosmological model, with constant positive spatial sections and coupled to radiation. We consider the…

Cosmology from an anti-de Sitter-Schwarzschild black hole via holography.
We derive the equations of cosmological evolution from an anti-de Sitter-Schwarzschild black hole via holographic renormalization with appropriate boundary conditions.
Quantum Raychaudhuri equation
We compute quantum corrections to the Raychaudhuri equation, by replacing classical geodesics with quantal (Bohmian) trajectories, and show that they prevent focusing of geodesics, and the formation…

Quantum dynamics with Bohmian trajectories.
TLDR
This work focuses on the crucial noncrossing property of Bohmian trajectories, which, numerically, must be given careful attention, which causes instabilities or leads to false simulations.

Quantumness beyond quantum mechanics
Bohmian mechanics allows us to understand quantum systems in the light of other quantum traits than the well-known ones (coherence, diraction, interference, tunnelling, discreteness, entanglement,…
Holographic cosmology from the first law of thermodynamics and the generalized uncertainty principle

WKB Analysis of Bohmian Dynamics
We consider a semiclassically scaled Schrödinger equation with WKB initial data. We prove that in the classical limit the corresponding Bohmian trajectories converge (locally in measure) to the…
